The UUP dump project allows users to create ISO files for Windows 11 (Canary, Dev, Beta, and Release Preview Insider channels, as well as production releases such as 22H2/22621.x and 21H2/22000.x), Windows 10 (22H2/19045.x, 21H2/19044.x, and 1809/17763.x) and Windows Server (22H2/20349.x and 21H2/20348.x). If you want to create Arm64 Windows ISOs for testing, you can do that as well. The cherry on top is that it can build multi-edition Windows images for consumer SKUs, and even output slipstreamed up-to-date ISOs, depending on the host OS.
